Chlorine Quantity for Pool Size
Having sparkling, clean water is every pool owner’s dream. Using chlorine is one of the most crucial ways to kill bacteria, help remove algae, and destroy nonliving organisms like sweat, oils, and cosmetics. But just how much chlorine do you need? Leslie's has put together an easy to read chart that breaks this down by types of chlorine and pool size for normal maintenance. Here are a few tips before we dive into the chart:
- If you are using chlorine products as your primary sanitizer, we recommended to maintain a residual chlorine level of 2.0-4.0ppm to effectively kill bacteria and prevent algae.
- You may want to adjust the chlorine quantity depending upon the weather, seasonality, and your pool usage.
- Stop by your local Leslie’s store for a FREE AccuBlue® 10-Point Water Test or use a Water Test Kit. This will help you understand your pool’s current chemical conditions and more specifically what your current Free Chlorine level is.
